Pants integration

Pants is a popular build system for monorepos with multiple languages and frameworks.

Namespace delivers fast Pants caching with minimal network delays between build runners and cache storage. This enables your Pants workflows to share and reuse build artifacts between different runs, regardless of how you've configured your build granularity, which substantially cuts down on overall build times.

Getting started

To use Pants caching, you can produce a ready-to-use configuration using the CLI:

Configure cache access

$ nsc pants cache setup --pants-toml=/tmp/pants.toml

This command generates short-term credentials, and sets up a Pants configuration file.

Use the Pants cache

$ pants --pants-config-files="['/your/own/pants.toml', '/tmp/pants.toml']" test ::

As demonstrated, you can pass multiple configuration files allowing you to combine your existing configuration with Namespace cache access.

GitHub Actions Example

jobs:
  build:
    runs-on: namespace-profile-default
  steps:
    - name: Setup Pants cache
      run: |
        nsc pants cache setup --pants-toml=/tmp/pants.toml
    - name: Pants test
      run: |
        pants --pants-config-files="['/your/own/pants.toml', '/tmp/pants.toml']" test ::

The pants.toml path can be customized if you need to use a specific configuration file.

How it works

The Pants remote caching solution employs a tiered caching approach, where the hot cache lives as close to the consumer (e.g. your CI job runner) as possible. The cold caching tier is backed by our high-performance artifact storage and enables Pants to retain a vast amount of cached artifacts.

Access to the Pants cache is granted through short-lived secure credentials.

Usage

Namespace accounts Pants cache usage in two categories:

Pants cache at rest
Active Pants cache usage
